A Solvable-On-Site cache. The info at the posted coordinates will give you all the data needed for the final coordinates.
The posted coordinates will bring you to the front of a fine Hudson institution: the public library. Some great stuff inside, and they have a great view of the river as well. (While you’re welcome to go inside during regular hours, you do not need to go inside the building to get the information for the final coordinates.)
The FINAL coordinates can be found at:
AAA = The street address of the building, minus 67
XX = The number of large black letters at the very top of the building, plus 41
Final is located in Lakefront Park, just a short walk from the Library. Logbook only (bison tube) – please use stealth as needed and place back as found. Enjoy the area!
